I have not requested any changes, and I am aware of the many updates between versions 2.2 and 2.9.
“…please install our latest version separately…”
My original post had been asking how I can install it separately. It explained that had been my intention — so I could compare 2.9 on a staging site (using plugin ‘SP Staging’, because I’m no developer) with 2.2 on the live site — but WordPress won’t install two identically named themes. So I can’t install it separately, to make this comparison!
Please be clear. Does ‘Please install our latest version separately then compare and proceed‘ actually mean ‘Yes, your only option is to overwrite the old version, see how much of your live site becomes broken, and attempt repairs/rebuilds in real time.’?
